When deploying cloud services, what are some of the deployment models you might encounter?

Question

What will be an ideal response?

Answer 1

ANSWER: The main deployment models you are likely to encounter are:
* public cloud-Service provided over public transmission lines, such as the Internet.
* private cloud-Service established on an organization's own servers in its own data center, or established virtually for a single organization's private use and made available to users over a WAN connection through some type of remote access. If hosted internally, this arrangement allows an organization to use existing hardware and connectivity, potentially saving money. If hosted virtually, the organization benefits from the usual advantages of virtual services, such as scalability and accessibility.
* community cloud-Service shared between multiple organizations, but not available publicly. Organizations with common interests, such as regulatory requirements, performance requirements, or data access, might share resources in this way. For example, a medical database might be made accessible to all hospitals in a geographic area. In that case, the community cloud could be hosted internally by one or more of the organizations involved, or hosted by a third-party provider. But it would not be made available to the public.
* hybrid cloud-A combination of the other service models into a single deployment, or a collection of services connected within the cloud. In the real world, the hybrid cloud infrastructure is a common result of transitory solutions. (In IT, "solution" refers to a product, service, or combination of products and services, and often includes extra features such as ongoing customer service.) An example of a hybrid cloud by design might arise when a company stores data in a private cloud, but uses a public cloud email service.
